The Hollow Crown

Love conquers all. For House Ashgrove, that's the family business.
Wren Ashgrove is the finest weapon her family has ever made. One touch to a man's temple, and he falls helplessly in love with her, right up until there's nothing left of him to love anyone. Eleven lords have already forgotten who they were. Eleven houses have been folded into her father's ledgers. Her mother says she's ahead of schedule.
But the dutiful daughter has a secret. After every conquest, Wren slips out at night with silver needles and her own blood to undo the damage, handing each man back a piece of himself. The price is a piece of her. Her seventh birthday is already gone, and she can no longer tell where the edges of herself are.
Next on her mother's list is the one house that has never fallen. For a hundred years, House Vayle has held the northern border and refused every Ashgrove overture. Now its new Castellan has asked for Wren by name, and her family has given her three months inside his mountain fortress to bring him to his knees.
Meet a lord. Touch him. Wait for him to forget his own name. Until Rowan Vayle doesn't.
Stranger still, he knows exactly what she is, and he doesn't flinch. Something ancient and hungry sleeps beneath his mountain, the Vayles won't say what, and the closer Wren gets to the truth, the more it looks like her family's gift and his fortress are made of the same magic.
Cursed with a power that only knows how to unmake people and stranded at the edge of the kingdom, Wren must do what no Ashgrove ever has: make a man love her without taking anything from him. And decide how much of herself she's willing to lose to keep him.

The Hollow Crown is a standalone slow-burn dark fantasy romance that combines the memory-stealing heartbreak of Eternal Sunshine of the Spotless Mind with an arranged-courtship romantasy and a dash of ancient mountain horror.
